In terms of appearance, I have no complaints; the case is neat and of good quality. Functionally, again, I have no complaints. I used it to do what I wanted (changing the battery in a watch with a screw-back case) and also, while I was at it, I used the tool for adding/removing bracelet links. Everything was fine.
The case is a bit cramped, though; I had to figure out how to arrange all the tools inside so I could take them out and put them back in comfortably. Overall, I am satisfied with the well-known balance of quality/price/functionality!!

I got the set purely for amateur use, I have some watches that needed their straps changed and the bracelets adjusted. I was struggling for hours with some fine screwdrivers I had from Wera without any luck, so I decided to buy the set. Excellent quality for a no-name brand, it had nothing to envy from the equivalent Facom screwdrivers I own, really, the adjustment took just minutes. The set also includes spare parts for the tips as well as the safety pins with springs, a super complete set, I generally recommend it if someone does small jobs and repairs tiny objects, you’ll want to fix other things besides watches.

On the downside, I would say that all the tools are held in place with elastic bands inside the case, which yes, keeps everything in place just fine, but they are tight enough that you can’t say you take them in and out easily.
